Skin grafts are done fairly frequently from cadavers. Usually not this extensive.
Further, since it is a very thin skin layer that is transplanted the likelhood of waking up looking like someone else is pretty thin (pun intended). The transplant will match your bone/muscle structure over a few weeks.
And this is a good thing, because otherwise Hillary would be wearing Al Gore's face next week.
